Let’s take a quick look at some of the differences between LTE and 5G in the area of functional splits between RAN and Core Network. We show and discuss high level splits of selected functionalities of the main “network functions/nodes” in both systems (discussing it from the 3GPP RAN3 WG perspective) from which we can make some conclusions on the differences between those two systems.

This post touches upon the 5G network functions (NFs) related to core network. Some of them look very similar to the corresponding functions in the previous generations’ core networks. This of course is not surprising, as the network always has to carry out some basic functions such as: communicate with the UE, store its subscription and credentials, allow access to external networks & services, provide security and manage the network access and mobility. However, we will also see some new functions, not present before, which are needed to enable the new network paradigms like slicing and service-based networking.
